l_oisr0_status.value = in32(OCB_OISR0);

When testing the RAS function of the OpenPOWER system, we found that after the Checkstop was triggered, "l_oisr0_status. fields. check_stop_ppc405" has a certain probability of being false, resulting in the FIR data not being collected. Excuse me?

1. Which module is this register set by?

2. The OCC determines whether to collect FIR data based on this value. At that time, it was determined that this value would be set up when the check stop?

What type of system and firmware level are you using?

Also, did you ensure the system rebooted after the checkstop was triggered?

[Grubby0624]

1. The firmware version is this commit: 58e422d
2. The system version is: Red Hat8.6 + Kernel is 4.18.0
3. I'm sure the system rebooted after the checkstop was triggered

What type of system are you using? Specifically, is this a P9 or P10 system?

[Grubby0624]

This is P9 system

[zane131]

Good, because P10 is a completely different analysis design. Let me poke around.
